In 1998, a team led by a former Harvard graduate student shocked the astrophysics world by publishing results that said the expansion of the universe, believed to be gradually slowing, was instead accelerating.

I don't want to alarm you, but there's a massive galaxy heading our way and will collide with us in a few billion years. But aren't most galaxies speeding away? Why is Andromeda on a collision course with the Milky Way?

(Phys.org) —In Jonathan Swift's 1726 book "Travels into Several Remote Nations of the World. In Four Parts," the miniature Lilliputians experience the world very differently from the giant Brobdingnagians.

The existence of the "Hubble Bubble" may explain, at least in part, the differing measurements for the expansion and therefore the age of the universe. That is the assumption of a team of physicists headed by Prof. Dr. Luca ...

Tonight, as the sun sinks below the horizon, the world's most powerful digital camera will once again turn its gleaming eye skyward. Tonight, and for hundreds of nights over the next five years, a team of physicists and astronomers ...

A five year quest is underway (3 September 2013) looking to solve the cosmic detective puzzle of why the expansion of the universe is speeding up. UK physicists and astronomers working alongside colleagues from around the ...
